Application filed December 12, 1911. Serial No. 665,327.

To all whom it may concern:

Be it known that we, JAMES OBLEIN and HENRY OBLEIN, subjects of the King of Great Britain, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Puzzle-Banks, of which the following is a specification.

This invention relates to an article having parts to be locked together, such as a puzzle bank in which the cover, door or removable part is held in locked position with respect to the body, and the invention refers to a novel combination lock of a type in which one or more freely movable independent bolts, or a plurality of interlocking bolts, or

a combination of free interlocking spring-- pressed bolts, are employed to hold the cover or door in closed position, and which are capable of gravitating to or from looking position by the tilting of the bank or other article as a whole, or by the tilting of the bank and the relative movement of the parts thereof, and hence by a series of tilting movements carried out in a predetermined order alone, or in connection with one or more turning movements of the bolt carry ing part with respect to a locking member with which the bolts engage, the bolts can be successively retracted to unlocking position for permitting the cover to be removed.

The invention has for one of its objects to provide a bank or other puzzle of neat and attractive design, comparatively inexpensive to manufacture, and embodying locking means of such a nature that the bank cannot be opened except by one knowing the combination of movements to be followed out to retract the bolts of the lock.

Another object of the invention is the provision of a simple, effective and novel looking means which does not depend upon the use of a key but merely the following out of a certain succession of movements of the part carrying the bolts so that the latter can be moved to unlocking position, the movement of the bolts to locking position being effected by a tilting movement however slight, of the part on which the bolts are mounted.

Another object of the invention is the provision of a bank having a rotary cover mounted in its top and carrying the combination lock which may be elther at the top of the body of the bank immediately under the cover or close to the bottom thereof,

there being in the latter form a bolt supporting disk or carrier which forms the bottom of the coin-receiving compartment of the bank.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention, Figure l is a perspective view of the bank. Fig. 2 is a perspective view of the cover with its attached parts removed from the casing of the bank, the bolt-carrying disk being shown in dotted lines to reveal the relation of the locking bolts. Fig. 3 is a central vertical section of the bank with the cover locked therein. Fig. 4 is a horizontal section taken immediately below the boltcarrying disk or bottom of the coin compart. ment and showing the bolts in that position where the combination of tilting movements are given to unlock the device. Figs. 5, 6,

7. S, 9 and 10 are sectional views showing the successive steps through which the boltcarrying part is moved to move the bolts to unlocking position. Fig. 11 is an enlarged sectional view of one of the bolts and guide sleeves therefor. Fig. 12 is a side view partially in section of another form of bank.

Fig. 13 is a sectional View on line 13-13, Fig. 12. Figs. 14 to 20, inclusive, are similar views showing the successive steps or movements necessary to unlock the cover of the bank. Fig. 21 is a view of the adjustable baffle or key. Fig. 22 is a further modification of the locking mechanism. Figs. 23 and '24 are views of another modification. Figs.

25 and 26 are horizontal and vertical sections, respectively, of another form wherein the bolts are carried by the body.

Similar reference characters are employed to designate corresponding parts throughout the views.

The invention is shown in the present instance as embodied in a puzzle bank, but it is to be understood that the invention can be applied to any other article where the looking together of two parts or elements is desired.

The bank shown in Figs. 1 to 12, inclusive, comprises abodyAwhich is preferably, although not necessarily, a cylinder having a closed bottom 1 and an open top to which is fitted a cover B that is in the present instance of such diameter as to fit within the body A, although this disposition of the cover is not essential, just so a complete closure is effected to prevent coins from being extracted from the body of the bank. On one element of the bank, preferably the body, is arranged an annular flange or equivalent means 2 with which the bolts of the combination lock are adapted to engage for locking the cover in closed position, and this flange is preferably, although not necessarily, disposed close to the bottom 1 but spaced therefrom a suflicient distance as to accommodate the locking bolts. The locking mechanism C comprises a plurality of bolts 3 that are carried by the cover either directly or indirectly; directly when the bolt-engaging member 2 is disposed at the upper port-ion of the cylinder A, but inclirectly when the part 2 is adjacent the bottom of the cylinder. Specifically the bolts are mounted on a carrier in the form of a disk 4 rigidly secured to a central stem 5 which is fastened to and extends downwardly from the center of the cover B, the disk being of such diameter that its peripheral portion will overlie and rest on the internal annular flange 2, so that in fact the cover B and attached parts are supported by such flange. The bolts 3 are approximately radially disposed under and parallel with the disk 4 and are each mounted in a sleeve or tubular holder 6 rigidly secured to the bottom surface of the disk 4. As shown in Fig. 11, the central portion of each bolt is formed with a central stem 7 and enlarged heads 8, and a portion 9 of the sleeve is pressed inwardly to form a key that engages between the shoulders formed by the heads, so that the bolts cannot slip out of the sleeves when the cover B and locking mechanism are bodily removed from the casing A. There may be different arrange ments and numbers of bolts to carry out the object of the invention, but the arrangement shown in the present instance comprises two groups of bolts 0 and c and two single bolts 0 and The bolts of each group are parallel with each other and those of one group are at right angles to the bolts of the other group. The single bolt 0 is diametrically opposite the group of bolts 0, while the single bolt 0 is diametrically opposite the bolts 0. When the bolts are in lockingposition, their outer ends project out of the sleeves or holders 6 and engage under the flange 2. It is not necessary for all the bolts to be simultaneously in projected position or engage under the flange 2, as merely one bolt in projected position will hold the parts locked together. Under the flange are baflles 8, 9 and 10, with which the projected bolts are adapted to engage so as to obstruct the turning movement of the cover with the locking mechanism and thus render difficult the relative movement of the parts to the initial position for beginning the combination of movements necessary to be carried out for unlocking the bank. The baflle or projec- .tion 8 has its inner face flush with the internal edge of the flange 2, whereas the bafiies or projections 9 and 10 are shorter. There can be any arrangement and member of baflies but what is shown in the drawings is preferred. The projection 8 forms a bolt stop or catch for holding one of the bolts in fully retracted position during certain stages in the combination of unlocking movements, as will be now fully explained.

In unlocking the bank, the cover which is equipped with a handle or knob 11 must be turned back and forth while the bank as a whole is tilted in diflerent directions until a position is reached where the bolt 0 will be in line with and engaging the bolt catch or stop 8, as shown in Fig. at. lVith the bank now in an upright position; that is to say, with its axis vertical, as when the bottom of the bank rests on the table, the bank is tilted forwardly so that the bolts 0 opposite the retracted bolt 0 will slide inwardly until the outer ends of the bolts pass from under the flange 2, and occupy the position shown in Fig. 5. The bank is then tilted back to a vertical position and next tilted to the right so that the bolts 0 will slide inwardly as indicated in Fig. 6. With the two groups of bolts thus retracted, the

knob 11 is turned to such a position that the bolt 0 will be close to the bolt catch or stop 8, as represented in Fig. 7, this turning being done while the bank is held with its axis vertical, and next the bank is tilted rearwardly so that the bolt 0 will slide inwardly and the bolts 0 will slide outwardly, as indicated, Fig. 8. It will be observed that the turning of the cover and attached parts from the position shown in Fig. 6 to that shown in Fig. 7 can be accomplished without thebaflies 9 and 10 interfering, the bolts nearest to such baflles being indrawn or retracted. lVhile the bolts occupy the position shown in Fig. 8, the cover and attached parts are turned far enough to bring the retracted bolt 0 into line with the bolt catch or stop 8, and thus while the parts are as indicated in Fig. 12, the bank is tilted forwardly to again retract the bolts 0 from under the flange 2, so that all the bolts will be retracted, as in dicated in Fig. 10, thus permitting the cover B to be lifted out. It will be observed that the rotary movement that has been given to the cover and its locking mechanism is about ninety degrees, so that the initially retracted bolt 0 never occupies a position where itcan slide outwardly during the steps represented by Figs. 6 to 10, inclusive.

In returning the cover, it is necessary that all the bolts remain in unlocking position or fully retracted in their respective sleeves. With the body A of the bank held vertically, the cover B held by the knob and carrying the locking mechanism is lowered vertically into the open top of the body A until the disk 4 rests on the flange 2, and a, slight tilting of the bank in any direction will cause one or more bolts to slide outwardly and engage under the locking flange 2. To facilitate the sequential movements to be carried out, the cover B may be provided with suitably designated marks or divisions and a corresponding arrangement of designated marks or divisions will be arranged on the body of the bank A. The bolts are so arranged with respect to the bolt catch or stop 8 that 14 on the cover will be opposite 1 of the body to begin the initial unlocking movement. The cover and body will remain in this relative position during the necessary movements for retract ing the two pairs of bolts 0 and 0. Then the cover B is turned so that 2 thereon will be opposite 2 on the body, when the bolts will be in the position shown in Fig. 7. After the following tilting movement to retract the bolt c the cover is again turned so that 1 thereon will be opposite l on the body, the bolts in this position being shown in Fig. 9. These two short turning movements are the only ones necessary in the combination for the particular arrangement of bolts herein shown. By arranging the numbers on the cover and body in different relative positions, a large variety of combinations can be obtained.

As has been hereinbefore intimated, different numbers or combinations of bolts may be employed as the locking means. For instance, bolts 0 alone can be used with the bolt 0 or bolts 0 with bolt 0 or bolt 0 with bolt 0 In fact, only a single bolt may be employed, but it will be obvious that the more bolts employed, the more diflicult will be the unlocking of the device. While the bolts are shown as carried by the cover element, it is obvious that they may be mounted on the body element of the bank and adapted to engage the cover element, but the operation will be practically the same as with the arrangement shown.

For the insertion of coins, the cover B has a coin slot Z) that is yieldingly closed by helical spring guards 7) fastened to the under side of the cover, said guards preventing the extraction of the coins.

In another form of the invention, as shown in Figs. 12 to 21, inclusive, the bolts may be arranged in one or more interlocking pairs so that each pair of bolts must be moved in a predetermined order to both locking and unlocking position, thus rendering the opening of the bank more diflicult, and furthermore these interlocking bolts may be combined with free bolts or with spring-pressed bolts or a combination thereof. Another feature of the construction shown in Fig. 12 is the fitting of the cover or top to the bank in such a way that it is impossible for the cover to be pried open or access otherwise had to the contents of the bank. The body A has an internal pocket at its top formed by a cylindrical flange 20 suitably secured at its lower edge to the body A, the space be tween the flange and body forming a pocket for receiving the annular depending rim or flange 21 on the cover 22. The cover is inserted or removed by a relatively axial movement, and on the cover is the usual knob or equivalent device The bolt-engaging flange 24 is arranged at the top of the body and may be carried by the cylindrical wall 20 of the cover rim receiving pocket, and the bolts are arranged in sleeves or equivalent carriers 25 fastened to the under side of the cover. This flange 24 is provided with a circular row of spaced openings 26, each large enough to receive a screw 27 for fastening the batl'les thereto. Concentric with the row of openings 26 is a row of smaller openings 29 adapted to receive a dowel pin 30 of the baflie 31, as shown in Fig. 21, such baflle having a tapped opening 32 for receiving the screw 27. catch or key baffle, as it is arranged with its The baflie 31 is the bolt boltengaging portion flush with the inner circular edge of the flange 24, but shorter baflles such as 33, Fig. 13, may be employed and the shorter baffles are secured in place by screws 27 also. There are three pairs of locking bolts shown, such as 34, 34 35, 35*; 36, 36; and also free or independent bolts 37 and 38 and a spring-pressed bolt 39. The bolts 34 35 and 36 have their inner ends formed with heads 40, and the coacting bolts 34, 35 and 36 are formed with pins 41 that cooperate with the heads of their companion bolts. By means of these heads and pins, the bolts must be moved in a predetermined order in order to unlock the cover, as will now be described. Assuming that the cover is locked and the bolts are in the position shown in Fig. 13, and it is desired to remove the cover; the bank as a whole is tilted so that the top will move to the left, thereby throwing out the bolts 34 and 35. as shown in Fig. 14, the free bolt 38 being in engagement with the key bafile 31. The bank is next tilted backwardly so that the bolt 34 will slide inwardly to the position shown in Fig. 15, and following this movement, the bank is tilted to the right so as to throw in the bolts 34 and 35, thereby engaging the pin of the bolt 34 with the head of the bolt 34 and also throwing the headed end of the bolt 35" into line with the bolt 35, as shown in Fig. 16. The bank is next tilted forwardly in order to cause the bolts 35 and 36 to slip inwardly to the position shown in Fig. 17, and while the three pairs of bolts are thus in retracted position, the cover with the attached parts is given a quarter turn to engage the bolt 34 with the key bafiie 31, as shown in Fig. 18, and now by tilting the bank forwardly, the bolts 36 and 37 slide inwardly from the position shown in Fig. 18 to that shown in Fig. 19. By this time, all the interlocking bolts are unlocked and in retracted position and the free bolts are also in retracted position, the spring-pressed bolt being the only one projected. The cover is now turned until the spring-pressed bolt 39 is brought into engagement with and pressed inwardly by the key baffle 31, as shown in Fig. 20. The bolts are now all retracted so that the cover can be lifted off. The key batlie 31, by reason of the plurality of open ings 26 and 29, can be placed at any desired position on the boltengaging flange 24 and consequently a large variety of combinations can be obtained. The bank and cover will have the combination numbers like the arrangement shown in Fig. 1, for instance.

In Fig. 22 is shown a combination of a I plurality of free or independent bolts and a single spring-pressed bolt, the combination necessitating a plurality of key baffies 42 and 43 so arranged that two free bolts can be held retracted, or the spring-pressed bolt and one free bolt at the same time. Assuming that the bolts are in looking position and it is desired to unlock the cover, the cover is turned to such a position that the bolts 44 and 45 are engaged with the key baffles 42 and 43, respectively. The bank is now tilted in such a manner that the bolts 46, 47, 48 and 49 are moved inwardly successively, and then by turning the cover so that the bolts 48 and 49 will engage the baffles 42 and 43, respectively, the bolts 50 and 51 can be thrown inwardly by tilting the bank in the proper direction. The bolts being now all retracted, the cover can be removed.

Another arrangement of bolts is shown in Fig. 23, wherein one bolt 52 has its inner end formed frusto-conical like the head of a wood screw, and the other bolt 53 that interlocks therewith is arranged with its axis at an obtuse angle to the axis of the bolt 52. A free independent bolt 54 may be used in this combination and still a key baflle is unnecessary. Obstructing or interfering baffles 55 may be used to prevent free rotation of the cover within prescribed limits when the bolts are projected to looking position. 0n the plate 56 that carries the bolts is a lug or catch 57 which engages under the flange 58 so that it is necessary to throw the lug or catch 57 into alinement with a recess 59 in the flange 58 before the plate 56, which may correspond to the plate 4, Fig. 3, can be lifted out even though the bolts be in retracted position. To unlock interlocking the bank with the arrangement of bolts shown in Fig. 23, the bank is tilted in such a position that the bolt 53 will be in proj ected posit-ion, so that its inner end will not interfere with the retraction of the bolt 52. The bank is now tilted to throw the bolt 52 inwardly to the position shown and then the bank is tilted to throw the bolt 53 inwardly where its inner end will engage behind the head of the bolt 52. Now the bank is tilted in a direction to retract the bolt 54, and during this tilting, the bolts 52 and 53 cannot slide outwardly because of their being interlocked. The cover and plate 56 are now turned to cause the catch 57 to register with the slot 59, in which position the cover and attached parts can be removed.

It has been stated hereinbefore that the bolts can be carried by the body of the bank instead of being located on the cover, as in the forms heretofore described, and this will be evident by reference to Figs. 25 and 26, wherein the bolts 60, 61, 62, 63, 64, 65, are mounted in sleeves 66 carried by the flange 67 that corresponds to the flange 24 in Fig. 12. On the cover is a disk or equivalent member 68 with which the bolts engage, this member being of such diameter as to freely enter the opening defined by the flange 67. On this plate'68 are arranged key and obstruction baffles 69 and 70, respectively, for the same purpose as the baflles heretofore described. To unlock the cover when the bolts are in looking position, the cover is turned to such a position that the bolt will be engaged with the key baffle 69. The bank is now tilted so that the bolts 63 and 64 will slide outwardly beyond the edge of the plate 68. The cover is now turned so that the key baflie 69 will engage the bolt 64 and then by suitably tilting the bank the bolts 61 and 62 will slide outwardly to unlocking position. The cover is again moved to cause the spring-pressed bolt to be pressed outwardly by the key baffle 69, thus permitting thecover to be lifted off.

It is possible to so arrange the locking bolts that the bank can be unlocked without being tilted, and one of the many arrangements of bolts that will unlock without tilting of the bank is shown in Fig. 23. To unlock the bolts, the bank will be held with its axis horizontal and the bolt 54 at the top, while the bolts 52 and 53 are in projected or looking position. The bank as a unit is given a complete revolution in such a direction that the bolt 52 will be thrown inwardly first and then the bolt 53, and during this revolution the bolt 54 will alsobe moved inwardly. While the bolts are all in unlocking position, the body of the bank alone is turned, while the bolt-carrying part is held stationary, and as soon as the lug 57 regis ters with the slot 59, the cover of the bank can be removed.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while we have described the principle of operation of the invention, together with the apparatus which we now consider to be the best embodiment thereof, we desire to have it understood that the apparatus shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.
